Large epidemiological studies showed that one of the most important causes of death in patients with rheumatoid arthritis (RA) is represented by cardiovascular disease. Thus, the presence of RA is associated with an increased risk of the occurrence of stable angina, myocardial infarction, heart failure and stroke. However, studies performed during the last years failed to bring us clear evidence regarding the role of traditional cardiovascular risk factors (hyperlipidemia, diabetes mellitus, hypertension, smoking and obesity) in the pathogenesis of cardiovascular disease in these patients. Recently, the role of inflammation and its mediators not only in the atherosclerosis plaque development but also in the mechanisms of vulnerable plaque was clearly demonstrated. From this point of view, recent studies showed that inflammatory cells and mediators of inflammation are both markers of an increased cardiovascular risk and unfavorable cardiovascular outcome, and also cardiovascular risk factors that act in an active manner in the processes that promote atherosclerosis. Taking into account the fact that RA is a systemic inflammatory status, recent reports demonstrated the involvement of inflammation mediators in connection with prothrombotic factors and endothelial dysfunction in the development of cardiovascular disease in RA patients. There are only scarce data in the literature regarding the benefice of cardiovascular risk reduction therapies in this group. Further studies are required for the refinement of the cardiovascular risk stratification algorithms and for the improvement of the cardiovascular risk management in rheumatoid arthritis.
大型流行病学研究表明,类风湿关节炎(RA)患者最重要的死亡原因之一是心血管疾病。因此,RA的存在与稳定型心绞痛、心肌梗死、心力衰竭和中风发生风险的增加相关。然而,过去几年进行的研究未能为我们提供关于传统心血管危险因素(高脂血症、糖尿病、高血压、吸烟和肥胖)在这些患者心血管疾病发病机制中作用的明确证据。最近,炎症及其介质不仅在动脉粥样硬化斑块形成过程中的作用,而且在易损斑块机制中的作用都得到了明确证实。从这一角度来看,最近的研究表明,炎症细胞和炎症介质既是心血管风险增加和不良心血管结局的标志物,也是在促进动脉粥样硬化过程中起积极作用的心血管危险因素。鉴于RA是一种全身性炎症状态,最近的报告表明炎症介质与促血栓形成因子及内皮功能障碍有关,参与了RA患者心血管疾病的发生。关于该组患者降低心血管风险治疗的益处,文献中仅有少量数据。需要进一步研究以完善心血管风险分层算法,并改善类风湿关节炎患者的心血管风险管理。
